Chrysanthemum plant named &#39;chisel time cerise&#39;

ABSTRACT

A new variety of pot Chrysanthemum plant named ‘Chisel Time Cerise,’ having a good uniform canopy of cerise pink spoon tip single flowers. The new variety has a medium tall vigor, free branching, uniform spreading habit and good foliage presentation.

LATIN NAME OF THE GENUS AND SPECIES

Botanical classification: Dendranthema grandiflora.

VARIETY DENOMINATION

The new Chrysanthemum variety denomination is ‘Chisel Time Cerise.’

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct cultivar of Chrysanthemum botanically known as Dendranthema grandiflora, and referred to by the cultivar name ‘Chisel Time Cerise.’

‘Chisel Time Cerise,’ identified as 21033-6, discovered as a whole plant mutation found in a controlled cultivated planting of the variety ‘Chisel Time Pink’ (U.S. Plant patent application Ser. No. 10/364,251).

The new variety ‘Chisel Time Cerise’ has been asexually reproduced by vegetative cuttings in Chichester, West Sussex, United Kingdom and the distinguishing characteristics are retained through successive generations of asexual reproduction.

BRIEF SUMMARY OF THE INVENTION

‘Chisel Time Cerise’ is a pot type of Chrysanthemum plant variety having golden quills with pink spoon tip single flowers.

Comparison with Parent

Plants of the new Chrysanthemum variety ‘Chisel Time Cerise’ are similar to the parent cultivar ‘Chisel Time Pink’ in plant habitat and growth rate. In side-by-side comparisons in Chichester, West Sussex, United Kingdom, under commercial practice, plants of the new Chrysanthemum variety ‘Chisel Time Cerise’ differed from plants of the parent cultivar ‘Chisel Time Pink’ in the following characteristics.

-   -   1. The new variety ‘Chisel Time Cerise’ produces golden quills         with cerise spoon tip single flowers whereas the parent cultivar         ‘Chisel Time Pink’ produces silver quills with pink spoon tip         single flowers.

Comparison with Other Varieties

Plants of the new Chrysanthemum variety ‘Chisel Time Cerise’ are similar to the cultivar ‘Scott’ (U.S Plant patent application Pending) in plant habitat and growth rate.

However, in side-by-side comparisons in Chichester, West Sussex, United Kingdom, under commercial practice, plants of the new Chrysanthemum variety ‘Chisel Time Cerise’ differed from plants of the cultivar ‘Scott’ in the following characteristics.

-   -   1. The new variety ‘Chisel Time Cerise’ produces golden quill         with cerise spoon tip single flowers whereas the cultivar         ‘Scott’ produces light pink quill with dark pink spoon tip         single flowers.     -   2. Plants of the new variety ‘Chisel Time Cerise’ have larger         and taller inflorescence than plants of the cultivar ‘Scott.’     -   3. The new variety ‘Chisel Time Cerise’ has a quicker response         time than the plants of the cultivar ‘Scott.’

BRIEF DESCRIPTION OF ILLUSTRATION

Typical specimens of the plant and flowers for the new Chrysanthemum variety ‘Chisel Time Cerise’ are shown in the accompanying digital photograph. The colors shown are as true as possible within the usual limits of this kind of illustration. FIG. 1 is a whole plant view of the new variety ‘Chisel Time Cerise’ grown in a pot. The plant shown in the illustration is 50 days from the commencement of Short Days.

DETAILED BOTANICAL DESCRIPTION

The following description of the new Chrysanthemum variety ‘Chisel Time Cerise’ is of plants grown in a greenhouse in Chichester, West Sussex, United Kingdom in the month of July. The cultivar has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in the environment such as temperature, length of day and light intensity, without any variance in genotype. The commercial classification of the new variety is a pot Chrysanthemum.

Plants of the new variety have been grown successfully under temperature conditions averaging about 19° C. at night and about 17° C. to 24° C. during the day under light conditions of about 5,000 to 6,000 foot candles. The plants respond well to the use of growth retardant, such as one B9 treatment at about 2 gm per liter. To produce a commercial product the plants may be pinched once with the center bud removed. The typical container size for commercial growth is 1 liter. It has been observed that the shelf life of the new variety is about 28 days with a response time of about 7 weeks. The new variety is suitable for growth in a temperature range of 15° C. to 25° C.

The new variety may be produced as a spray. The following description is with respect to a plant produced as pot. In the description of this new Chrysanthemum variety, color values have been taken from The Royal Horticultural Society Colour Chart (R.H.S.C.C.).
